I have a brown mallee burl that I would like to turn, but want to leave the back natural without flattening a spot, creating a tenon, or a recess. Is this possible? If so, how? I have searched various media, but haven't come up with a solution. I'm assuming it probably can't be done.
The burl is about 14" long and not quite as wide.
Thanks for any assistance you can provide.
